The pectoral muscles can produce a trigger point causing pain much like a heart attack in both intensity and quality.
If you are ever in doubt whether you are having a heart attack, you should call 911 and be evaluated for that condition in a hospital where tests can show definitively whether or not your heart muscle is involved.
After having been cleared of a heart attack by qualified personnel, a next step should include determining whether a trigger point within the pectorus muscle is causing the pain. A qualified neuromuscular massage therapist can help determine if this is the cause of your pain.
